This Tiny Robot Walks, Crawls, Jumps and Swims. But It Is Not Alive.
Researchers in Germany have developed a robot that is about a seventh of an inch long and looks at first like no more than a tiny strip of something rubbery. Then it starts moving. The robot walks, jumps, crawls, rolls and swims. It even climbs out of the pool, moving from a watery environment into a dry one.
